## What is EP?

Equation Pyramid is a number logic game where players must select 3 non-repeating tiles from a grid and arrange them in order to form an equation that exactly matches the target number at the top of the pyramid. With a mix of addition, subtraction, multiplication, and division, it sharpens your calculation and logical thinking skills.

Single Player Mode:
Each puzzle has a 3-minute time limit. Try as many times as you want until you solve it and earn points!
You can register an account to permanently save your score and rankings and compete with players around the world!

Dual Player Mode:
Two players compete. Each round has a 3-minute timer. Press the "Buzz In" button before answering—whoever answers correctly first scores a point! Multiple rounds supported; highest score wins!

Game Rules Summary:
A target number is shown at the top of the pyramid
Select 3 non-repeating tiles from the bottom layer and arrange them in order
The first tile’s operator is ignored; only the number is used
Calculation follows multiplication/division first, then addition/subtraction
The system automatically checks your answer and gives instant feedback

Challenge yourself with Equation Pyramid and unleash your logic potential to reach new intellectual heights!
